Flat To Pitch Roof Conversions

Lightweight and easy to handle and fix, Decra tiles are ideal for flat to pitched roof conversions. Often no additional strengthening of the structure is required to support the Decra roofing system, as it is lightweight. Intricate detailing and installation on roofs even many storeys above ground, may be achieved quickly and cost effectively, reducing future maintenance requirements and enhancing the appearance of the building.

Why Convert?

Flat roofing is a tried and tested method of roofing a building. For centuries flat roofs have adorned all types of building from civil facilities, through industrial structures to residential buildings. Coupled with advances in materials and manufacturing technologies in the last 30 years, there has never been a better time to specify a flat roof.

There are scenarios where a flat roof is quite simply not the best solution. For example, a roof system that has been in place on a school building for many years, with inferior and decrepit components, may well have developed degradation problems that mean installing another modern flat roof system is not an economical or indeed viable option.

Flat to pitched roof conversion isn’t just the replacement of one type of roof for another. Instead, it allows re-modelling of the roof profile which, not only enhances the overall aesthetics of a building, but can also provide thermal benefits, enhance security and of course, improves surface water drainage. By installing such a system combined with a Decra tile, a pitched roof can achieve a life expectancy of up to three times that of a flat roof.
